The crustacean known as Harryplax severus was found 20 years ago in Guam by the late researcher Harry Conley, but it wasn’t identified as a new genus and species until more recently.

Biologists Peter Ng and Jose Christopher E. Mendoza, who recently identified the crab as a new species in the journal ZooKeys, explained that they named the crab after both Harry Conley and, as first reported by Live Science, Mendoza’s “favorite fictional character,” Severus Snape.

The specific epithet, severus (L., harsh, rough, rigorous), alludes to the rigorous and laborious process by which this crab was collected. It is also an allusion to a notorious and misunderstood character in the Harry Potter novels, Professor Severus Snape, for his ability to keep one of the most important secrets in the story, just like the present new species which has eluded discovery until now, nearly 20 years after it was first collected.

Although Harryplax is mostly in reference to Harry Conley, Ng and Mendoza write that the name also honors the-one-and-only Harry Potter.

The name is also an allusion to a famous namesake, Harry Potter, the magical hero of the popular book series by J.K. Rowling, and Mr. Conley’s uncanny ability to collect rare and interesting creatures as if by magic.
